Flagger Ahead Sign: Meaning and What to Do

The orange diamond with a figure holding a flag warns that a person is directing traffic ahead, usually where a work zone squeezes two directions into one lane. The flagger's STOP and SLOW paddle is a portable, human-operated traffic signal.

The sign

Flagger Ahead Sign

  • MUTCD W20-7a
  • Diamond
  • Orange with a black flagger symbol
  • Work zone sign

The rule that makes this sign matter: a flagger's direction overrides signs and signals. If the flagger shows STOP, you stop, whatever the posted controls say, and you move only on the SLOW face or a clear wave-through. Disobeying a flagger is treated like running a signal, and in a work zone often carries higher penalties.

What to do

What to do when you see the flagger ahead sign

Slow down immediately and be ready to stop where the flagger stands. Obey the paddle without negotiation: STOP means stop and wait, SLOW means proceed at reduced speed along the path shown. Keep your eyes on the flagger while moving through, since instructions can change mid-zone.

The signs it is confused with

Questions pair it with the general Road Work sign that opens the zone, and probe the override rule: between a green light, a posted limit, and a flagger, the flagger wins. The pedestrian-figure warning signs look similar at a glance, but only the flagger holds a flag or paddle, on an orange background.

Questions

Questions about the flagger ahead sign

What does the flagger ahead sign mean?

A person is directing traffic ahead with a STOP and SLOW paddle, usually where a work zone reduces the road to one shared lane. Slow down and be ready to stop at their position.

Do flagger instructions override traffic signs and signals?

Yes. A flagger's direction takes precedence over posted signs and signals in the zone. If the paddle says STOP, you stop, even if everything else suggests you could proceed.

What do the two faces of the paddle mean?

STOP means come to a complete stop and wait at the flagger's station. SLOW means proceed, at reduced speed, along the path the flagger indicates. There is no third option and no rolling through a STOP face.

Why do work zones use human flaggers at all?

Because the traffic pattern changes minute by minute: alternating one-lane traffic, trucks entering, crews moving. A person can meter traffic in real time in a way fixed signs cannot.

How does the flagger sign appear on the written test?

As identification of the orange symbol and as the override rule in scenario form: who do you obey when a signal and a flagger disagree. The tested answer is always the flagger.
